Oct 11, 1949. 1.. SALFISBERG PACKAGE Filed Feb. 26, 1946 A 'rroewsy Patented Oct. 11, 1 949 PACKAGE Leroy L. Salfisberg; South Orange, N. J., asslgnor to Ivers-Lee Company, Newark, N. J., a corporation of Delaware Application February 26, 1946, Serial No. 650,195 3 Claims. (Cl. 206-56) This invention relates in general to packages whose walls are formed of thin flexible material, for example, paper and the like, and more particularly the invention contemplates a package of the type that includes an envelope or bag having sheets of flexible material sealed together to form walls and hinged cover flaps attached to the envelope.

In known packages of this type, the covers comprise pieces of material separate from but folded around the envelope or bag as shown for example in Patent No. 2,239,040. Such packages require a separate and special operation for attaching the covers and it is not practical to use both the inner surfaces of the cover flaps and the outer surfaces of the envelope walls for indicia, such as directions for use of the package contents.

Therefore one object of my invention is to provide a package of this general character which shall embody novel and improved features of construction wherein each wall of the envelope and one flap shall be integral and shall thus provide a continuous unbroken surface for receiving indicia thereon.

Another object is to provide a package of this character with hinged covers that provide means for carrying indicia on their inner and outer surfaces and at the same time fold over the package to protect the same against damage.

A further object is to provide a package of this character that is simple in construction and inexpensive to manufacture.

Other objects and advantages of the invention will appear from the following description in conjunction With the accompanying drawing in which:

Figure 1 is a perspective view of a package constructed in accordance with my invention, showing the covers in closed or folded position.

Figure 2 is a view similar to Figure 1, but showing the covers open or unfolded.

Figure 3 is a sectional view taken on the plane of the line 33 of Figure 1.

Figure 4 is a view similar to Figure 3, showing a modification of the package; and

Figure 5 is a similar view showing another form of the package.

Broadly, my invention contemplates a package comprising two approximately co-extensive sheets of packaging material sealed to each other for one-half their area to form a commodityreceiving compartment, the remaining unsealed areas of said sheets forming hinged covers, each hinged cover with the adjacent sealed area forming a continuous surface for receiving indicia.

Referring to the drawing, two sheets I and 2 of packaging material such as thin, non-transparent paper or other suitable material are placed in overlapping relation. The overlapped sheets for substantially half their area are sealed together to form a commodity receiving compartment A centrally of said area. The sealing may be effected by interlocking or interdigitating the sheets by crimping dies so as to form a comparatively rigid unitary bonding formation. The compartment is circular in formation and is provided with a flat shoulder 3 converging into the sealed area. If desired, one or more of the edges of the sealed area may be slotted to facilitate tearing into the compartment.

The remaining uncrimped portions of the sheets are free of each other and are folded outwardly as at 4 and 5 over the outside surfaces of the compartment and sealed area of the package thereby forming hinged covers site sides of the envelope. The fold lines 4 and 5 provide substantially flat hinge joints when the covers are open or unfolded as shown in Figure 2. The outer surface of the inner envelope and the inner surface 8 of the adjacent unfolded cover being substantially in the same plane and the sheets being formed of opaque material there is provided a suitable flat continuous surface on which any suitable indicia may be printed. For example, on such inner surface 8 and adjacent outer surface of the package, instructions for using the contained commodity 9 may be printed at the same time and to read in continuity. The opposite outer surface in of each cover may also be provided with indicia such as a trade mark and/or advertisement of the manufacturer or seller of the contained commodity, or such surface may contain instructions which are continued on the inner surface thereof and on the package. Various other forms of indicia may of course be provided as required.

The covers are co-extensive with the package and when folded over as shown in Figure 1 protect the package against damage.

If desired, they can be torn off easily and neatly, for example, should a doctor desire to hand a patient the envelope and retain the directions or advertising on the cover.

In Figure 4, is shown a modification of the package wherein the hinged covers 6 and 1 are sealed to the juxtaposed sides of the sheets I and 2, respectively, adjacent the folds 4 and 5 as indicated at II. This construction has the effect of holdingthe covers 6 and 1 in snug contact with the sides of the commodity-receiving 6 and 'l on oppoe compartment and tends to accidental unfolding of the covers.

Another form of the package is illustrated in Figure 5, which is substantially the same as the package of Figure 3 in all respects except that the free edges of the covers I: and II, which correspond to the covers 6 and I, extend beyond the edges of the sheets II and I5 opposite the folds 4 and 5 and are sealed together as indicated at [6 ma zone in spaced relation to said edges of the sheets I4 and I5. This construction has the effect of positively holding the covers in snug contact with the commodity-receiving compartment and positively prevents accidental unfolding of the covers.

For opening the package, the sealed zone IB may be torn oif, and to facilitate such tearing,

.a line of scoring or perforations ll maybe provided at the juncture of the sealed zone IS with a ment centrally of said sealed areaand toprovlde 3 a rigid unitary area, the remaining areas of said sheets being folded outwardly to form hinged covers on opposite sides of the sealed area, the fold lines of said covers being substantially fiat when the covers are in open flatwise position so that each outer surface of said sealed area and 5 the adjacent inner surface of one of said covers provide a continuous unbroken surface for receiving ind icia thereon, said covers being coextensive with the sealed area for protecting the compartment against damage. 10 2. A package comprising an envelope including two opposed layers, of material sealed together in zones forming a commodity compartment between them having a commodity therein, each layer having an integral extension beyond said 15 envelope which is folded outwardly and away from the other extension into overlying relation to said compartment to form a cover for one side of said envelope. 3. The package as defined in claim 2, wherein said outwardly folded extensions extend and are sealed to each other beyond the edges of said envelope opposite said folds.
